Water damage is one of the most common causes of

building repairs. Not only are such repairs costly, but

in many cases damage is impossible to correct.

Further, water intrusion in building structures creates

a favorable environment for the development of other

serious problems – such as mold, dry rot and decay.

Proper water management is the essential first step in

controlling mold, dry rot and decay.

The easiest way for water to get into structures is

through windows, doors and other detail areas where

no water protective building components are installed.

To minimize the possibility of water entry, all critical

detail areas should be flashed using the appropriate

flashing materials and following the proper installation

techniques.

Why Use Grace Flashings on Windows, Doors and Other Critical Detail Areas

21

• To protect windows, doors and other critical areas

from water intrusion

• To control water and moisture – the first step in

controlling mold

• To comply with new codes and standards

• To ensure high quality work

• To minimize costly call-backs for repairs

• To lower energy costs by eliminating air infiltration

and exfiltration

n Grace Vycor Deck Protector®

All of the shaded areas below can benefit from the application of Grace VycorSelf-Adhered Flashings (beneath the finished siding and decking) and GraceUnderlayments (like Grace Ice & Water Shield) for the roof. Consider Grace Vycor Self-Adhered Flashings for your critical non-roof flashing details (windows, doors, decks).

• Fast and easy to install – simply peel off the release paper

and adhere the membrane

• RIPCORD – a Split Release

on Demand feature, is a thin cord

embedded in the rubberized asphalt,

which allows for ease of installation

and proper integration with house-

wrap/building paper

• Exceptional adhesion capabilities and sealability to most

common substrates

• Seals around fasteners ensuring no water infiltration

at penetrations

• Forms watertight laps, even at the seams in the flashing

• Easy to use, with clear measurement markings on the

membrane surface facilitating the installation procedure

• ICBO approved. Meets the performance requirements for

adhesive flashing materials (Report ER-6141)

• Grace Vycor Plus is based on the same proven 25+ year

technology as Grace Ice & Water Shield – the industry

leader in roofing underlayments

What Are the Unique PerformanceAdvantages of Grace Vycor Plus?

There are a number of flashing materials avail-

able on the market today. The major

difference between them is the level of water-

proofing performance they provide. Grace

Vycor Self-Adhered Flashings are comprised of

a high-density, polyethylene carrier film and a pressure-sensitive

adhesive layer, both of which

have unique performance

advantages.

Grace Vycor Plus is the product

of choice of well-respected

construction professionals be-

cause of its superior water-

proofing properties and ease of

application.

• ASTM E2112-01* and AAMA 2400-02* recom-mend the use of a minimum 9 inch wide flashingmembrane beyond the rough opening.

• Grace recommends a 12 inch wide flashing mem-brane for proper waterproofing of the windowsill, providing a drainage plane in the rough open-ing.

• Remove any weather-resistive barrier from sillarea prior to membrane installation for full adhe-sion of the membrane to the structural sill.

• Refer to “Table I – Flashing Lengths and CutFormulas,” (page 8), to determine appropriateflashing lengths.

• After the membrane has been installed, roll firmly into place.

• Install membrane such that all laps shed water (following theshingle principle). Always work from the low point to the highpoint.

• Mechanically fasten the membrane at vertical terminations, asnecessary.

• Weather-resistive barrier refers to housewrap, building paper/felt, Perm-A-Barrier

®

, etc.

• Windows/siding should be installed according to the standardsset by the window/siding manufacturers and/or respective organizations.

• Apply Grace Vycor Self-Adhered Flashings only in fair weather when the air, surface and membrane temperatures are at a minimum of -4°C (25°F). For temperatures below 5°C (40°F),keep material warm until use. (Refer to Technical Letter 3.)

• Install directly onto a clean, dry and frost-free surface.Remove dust, dirt and debris. Surfaces shall be smooth andcontinuous without voids, damaged or unsupported areas.

• Priming is generally not required for most substrates pro-vided they are clean and dry. However, on concrete,masonry and DensGlass Gold

®

, apply Perm-A-Barrier WBPrimer at a coverage rate of 6-8 m2/L (250-350 ft2/gal). If adhesion is found to be marginal, also prime wood composition and gypsum sheathing with Perm-A-BarrierWB Primer at the same coverage rate.

PRECAUTIONS AND LIMITATIONS

Precautions and Limitations

2221

Some solvents in certain caulking may be incompatible with

the adhesive in Grace Vycor Self-Adhered Flashings. Refer to

Technical Letter 1, “Chemical Compatibility with Other Building

Materials and Sealants,” page 51.

If fasteners are removed, leaving holes in the membrane, it

must be patched with another piece of membrane.

Consistent with good construction practices, install the

membrane such that all laps shed water (following the

shingle principle). The top membrane layer should go over

the bottom layer. Always work from the low point to the

high point.

Apply Grace Vycor Self-Adhered Flashings only in fair

weather when the air, surface and membrane are at

temperatures of -4°C (25°F) or higher.

SAFETY, STORAGE AND HANDLING

Grace Vycor Self-Adhered Flashing and accessory products

must be handled properly. Read all product labels and

Material Safety Data Sheets (MSDS) – see our web site at

www.graceconstruction.com for proper handling and

disposal. Deliver all materials in manufacturer's unopened

packages and store all materials under cover. Do not double

stack palletized material.

Grace Vycor Self-Adhered Flashings are designed for

critical non-roof flashing details. DO NOT install

on the roof.

Grace Vycor Plus and Grace Vycor V40 are slippery –

DO NOT walk on their surface. The surface of Grace

Vycor Deck Protector, although treated with a skid-resis-

tant coating, could also be slippery. Use special care and

take all necessary fall protection precautions when walk-

ing on the membrane.

Release liners are slippery. Remove from work area

immediately after membrane application.

Do not leave Grace Vycor Self-Adhered Flashings perma-

nently exposed to direct sunlight. Maximum

recommended exposure time is 30 days.

Due to its slight asphaltic odor, DO NOT apply this

product where the membrane is exposed to interior

living space.

Grace Vycor Self-Adhered Flashings should not be used in

hot desert areas in the Southwestern United States.

Grace Vycor Self-Adhered Flashings are not compatible

with plasticized polyvinyl chloride (flexible PVC). Certain

metal window applications with integral nail fin may

have specific limitations. Contact window manufacturer

for specific application instructions required when using

a bituminous-based flashing.

WHAT THE PROS SAY

Jim Standish, Managing Director

The Finishing Touch Inc.

“Grace Vycor Plus is the best self-adhered flashing tape

material on the market. We use Grace Vycor Plus Tape for

all of our flashing needs. Using Grace Vycor Plus Tape

eliminates your call-back problems."

Bill Gallagher, Owner

The Boston Building Company

“Grace Vycor Plus is the best window and door flashing

membrane in the market. Why? It's the only material that

sticks at colder temperatures and it is bullet proof against

wind-driven rain and snow. With Grace Vycor Plus you can

rest assure there won't be any water intrusion."

John Kurowski, Owner

Kurowski Development

“When it comes to installing flashing tapes around win-

dows and doors, it is important to use quality materials

installed properly. Grace’s instructional CD clearly sup-

ports the old saying ‘a picture is worth a thousand

words.’ That kind of field support helps me instruct our

trade contractors better, and helps me be a better builder.

So, when it comes to door and window flashing tapes,

flash it, flash it right, wrap it tight, with Grace Vycor Plus

flashing tapes.”

Bill Fox, Senior VP of Construction

Davis Homes, LLC

“It’s critical in constructing homes in the Midwest that

the integrity of the building envelope is preserved and

protected against water infiltration. Installing Grace Vycor

Plus Self-Adhered Flashings at all vulnerable points,

including around doors and windows, has made our job

a lot easier at Davis – no more costly call-backs

due to unwanted water and moisture damage. Thanks

to Grace, we now have a product with ultimate sealing

performance.”www.graceconstruction.com

“Without question, the most important materials that can be

used in modern home construction are properly selected

housewraps/membranes that, when used together with a

flashing system, can stop damage that occurs from liquid

water breaching the claddings. Installation methods of

these materials are critical, as improper installation can

render the materials useless.

The key is to have one building envelope, integrated and

protecting the structure from water damage, from the roof

to below the foundations.”

WHAT THE PROS SAY

Tips from the Pros... you’ll save time and money

2625

Joe Lstiburek, Ph.D, P. Eng.

Principal, Building Science Corp.

“Mold problems cannot exist without water problems. No

water problems, no mold problems. The sooner the water

is directed out of the building structure, the better. The

best expression of this concept is a flashing. Flashings

are the most underrated building enclosure component

and arguably the most important.

Window and door components within the opening can

leak, especially if installed improperly or if they are of

poor quality. Even the best made windows and doors can

leak as they age. Therefore, all windows and doors, as

well as all other critical detail areas, have to be properly

flashed. Self-adhered flashing membranes, such as Grace

Vycor Plus Tapes, are the first line of defense against

water damage of building structures.”

Technical Letter 1Chemical Compatibility with OtherBuilding Materials and Sealants

Frequently during the design of an assembly, thedesigner will question the chemical compatibility ofself-adhered flexible flashings with other materials.Grace Vycor

®

Self-Adhered Flashings (Grace VycorPlus, Grace Vycor V40 and Grace Vycor Deck Protector) are chemi-cally compatible with most substances and products that arenormally present in common application environments. GraceVycor Self-Adhered Flashings are compatible with acids, bases,and salts.

Generally, there is no chemical compatibility issue if a materialcontacts the high-density polyethylene surface of the self-adheredflashing. If the contact area is the rubberized asphalt component ofthe flashing, there is need to investigate further. As a general rule,the material must be sound, functional and firmly bonded to thesubstrate.

The design of the connection between the two materials willvary depending on the composition of the material. Some of themore common materials are detailed below.

Building MaterialsGrace Vycor Self-Adhered Flashings are applied directly to exteriorsheathing panels such as plywood (including fire-treated plywood),oriented strand board (OSB), exterior gypsum board, glass mat sur-faced gypsum board, and extruded polystyrene. Grace flashingsare compatible with chromated copper arsenate (CCA), alkalinecopper quaternary (ACQ), ammoniacal copper zinc arsenate(ACZA), pressure-treated woods and pressure-treated plywoods.

Window & DoorsThe rubberized asphalt of Grace Vycor Self-Adhered Flashings iscompatible with rigid polyvinyl chloride (PVC), but not plasticizedpolyvinyl chloride (flexible PVC). Some arched/round shape win-dows may use a flexible PVC nailing flange. Consult with thewindow manufacturer to determine if the nailing flange is con-structed of flexible PVC.

Note: Per ASTM E2112, “The application of sealant to the exteriorface of the (window) flange is not necessary if using self-adhesivetype flashing over the mounting flange.”

Weather-Resistive BarriersGrace Vycor Self-Adhered Flashings are applied to the structuralsubstrate. They should be integrated with the weather-resistivebarrier to form water-shedding laps.

Grace Vycor Self-Adhered Flashings are compatible with thefollowing weather-resistive barriers:

• Spun-Bonded Polypropylene • Polyurethane Coatings• Spun-Bonded Polyethylene • Polyethylene Sheet/Visqueen• Red Rosin Paper • Asphaltic Dampproofing• Asphalt Saturated Felt • Perm-A-Barrier®

Wall Membrane

Sealant and Caulking MaterialsMost sealants are chemically compatible with Grace Self-AdheredFlashings provided that the sealant is applied to the high-densitypolyethylene film component of the flashings.

The following sealants are chemically compatible with theadhesive side of Grace Vycor Self-Adhered Flashings if the specificformulation does not contain hydrocarbon solvents:

• Silicone • 1-Part Polyurethane• Acrylic • 2-Part Polyurethane• Butyl

Remove excess sealant prior to installing flashing.

Non-Compatible MaterialsGrace Self-Adhered Flashings are not compatible with the following substances:

• Creosote • Hydrocarbon Solvents• Pentachlorophenol • EPDM• Polysulfides • Flexible PVC• Diesel Fuel • Uncured Neoprene• Gasoline/Oil • High concentrations of pitch

(resin from soft wood)PrimersOnly Grace approved primers should be used with Grace Self-Adhered Flashings. Grace Vycor Plus, Grace Vycor V40 and GraceVycor Deck Protector are compatible with the following Graceprimers:

• Perm-A-Barrier®

WB Primer • Bituthene®

Technical Letter 2Exposure Guidelines

Grace Vycor®

Self-Adhered Flashings (Grace Vycor Plus, GraceVycor V40 and Grace Vycor Deck Protector) are not intended to beleft permanently exposed to direct sunlight. Flashings should becovered and protected from sunlight as soon as possible. GraceVycor Self-Adhered Flashings may be left exposed up to 30 days ifnecessary, to accommodate construction scheduling or weatherproblems. Exposure time of up to 60 days may be acceptablewhen Grace Vycor Deck Protector is used for corrosion protection.It is recommended that this product be trimmed around the con-nector to limit direct UV exposure (for instance at post bases).

During the time period the product is left exposed there aretwo primary factors that could affect the flashing: heat and ultravi-olet (UV) radiation. Product performance should not change, butthere may be some changes in appearance depending on the cli-mate and length of exposure.

After 30 days exposure, it is possible for the membrane to appear slightly wrinkled. There may be a small amount of curlingat the edges of the membrane. Before covering the membraneafter such a long exposure, the flashing should be inspected toensure that any wrinkling, curling or other movement that hastaken place has not affected typical detail areas. Visitwww.graceconstruction.com for a complete list of common flashing details.

If a wrinkle extends to the edge of an overlap, it must be cut,pressed down, and patched before the wall covering is installed.Extend a patch 6 inches in all directions, where applicable, pastthe damaged area.

If exposures longer than 30 days are anticipated, please con-tact your local Grace representative.

Technical Letter 3Cold Temperature Applications

The long-term adhesion of self-adhered flashings will be unaf-fected by lower temperatures provided that the initial adhesion issatisfactory (such that the flashing remains adhered until the wallor deck covering is installed). The information below provides use-ful guidelines to promote initial adhesion at colder temperatures.

Grace Vycor Self-Adhered Flashings (Grace Vycor Plus, GraceVycor V40 and Grace Vycor Deck Protector) can be applied whensubstrate, air and membrane temperatures are 25°F or above.When installing these products in cold or marginal weather conditions, the following guidelines can improve initial adhesion:

• Ensure that substrates are free from frost, dust, or other conta-minants

• Keep material warm until use• Gently warm membrane adhesive using a hot air gun • Roll the entire membrane firmly paying special attention to

seal all seams• Mechanically fasten the membrane at all vertical terminations

using only smooth shank fasteners• Prime substrate with Perm-A-Barrier
